Question

The relationship v=u+at

Answer 1

Answer:

Here u represents the initial velocity, v the final velocity, a the uniform acceleration, and t the time.

The dimensional formula of u is [M

0

LT

−1

].

The dimensional formula of v is [M

LT

−1

].

The dimensional formula of at is [M

0

LT

−2

][T]=[M

0

LT

−1

].

Here the dimensions of every term in the given physical relation are the same, hence the given physical relation is dimensionally correct.
